It is really hard to say without knowing the source of manufacture (i.e. facility). Most heat exchanger manufacturers either have facilities in China, or contract out to Chinese manufacturers. Around 2007 I had a difficult time locating a decent D1 radiator, resulting in my parts supplier providing four different radiators, from three different manufacturers, all in the course of 6 months. The last one came from Nissens A/S and is still running fine.
I'm kind of dreading the point I'll need to find one form my RRC...
